Abstract
The purpose of this research is to show the relevance of the notion of 'skepticism' for the philosophy of art. From Modernism on, art is plagued by a lack of confidence in the traditional conventions and by an instability of the criteria governing the membership of an object to the category of 'art'. The notion of 'skepticism' is linked to the concept of 'expression': if art faces a form of skepticism, then the emphasis on the personal expression of artists and audiences leads to a solution to the skeptical problem. The dissertation is divided into two parts: The first part, entitled 'Cavell, philosophy and skepticism', is a long Overture. With constant reference to the philosophies of Wittgenstein and Cavell, all the main themes of the dissertation are introduced: modernity and tradition, style and method, skepticism and ordinary, skepticism towards other minds (skepticism and expression). The second part, entitled 'Philosophy of Art and Modernism', isolates a line of thought from the writings of Tolstoy, Wittgenstein and Cavell. The three thinkers apply to art the concepts discussed in the previous part. Tolstoy, Wittgenstein and Cavell are linked by an awareness of a rupture in the relationship between contemporary art and tradition - a fracture that will be easy to recognize as skepticism in the art - and by the discovery of a similar solution. In particular, the notion of 'expression' will solve the skeptical problem. The first part is preparatory to the second because it contains all the themes and the concepts to be applied to art. The second part is analogue to the first: skepticism in the art, in fact, has a profound analogy with skepticism towards other minds. This analogy is made explicit in the conclusion, with a reference to attempts to define art
